Successful customer acquisition often takes place through digital channels such as Facebook and Google AdWords. The central element here is the Return on Investment (ROI) – it reveals how effective your advertising expenditures are and whether they are worth it for you. With a simple calculation method, you can quickly determine when and how much profit you can achieve from your advertising spending.
Key Insights

- With an effective strategy and the right values, you can optimize your ROI.
Step-by-Step Guide
1. Understand the Basics of ROI
Start by understanding the basic idea behind ROI. For example, if you invest €100 in advertising, you should receive more than €100 back. A positive ROI indicates that your advertising expenditures are worthwhile.

2. Calculate the Initial Values
To calculate ROI, you need some basic values. This includes the amount you spend on advertising and an estimate of the revenue you can generate from this advertising. Also, keep track of how much you make on average for each order and what costs are associated with it.

3. Use the Return on Invest Calculator
A practical tool for calculating your ROI is a Return-on-Investment calculator that you can use in the form of an Excel spreadsheet. This spreadsheet helps you input the various variables and see how different scenarios affect your ROI. You can easily copy the spreadsheet into Google Docs and use it for your calculations.
4. Consider the Customer Lifetime Value
The Customer Lifetime Value (CLV) is the total value that a customer brings during their entire relationship with your company. This is especially important when you think about follow-up orders. For example, if a customer has an initial order of €450 but later places a follow-up order of €250, this is essential for your calculations.
5. Calculate Cost per Profit
After entering the initial values, you determine your profit from each order. For instance, if the advertising costs are €500, and you gain €450 in orders, you must consider that this initially leads to a loss. But if the customer places a follow-up order, the profit will swing back into the positive.
6. Vary Your Calculations
Test different scenarios by changing the order value or accounting for additional costs. If you have €10 in additional costs for each order, your profit will be affected accordingly. This gives you a better understanding of how your advertising impacts profits.
7. Analyze the Conversion Rate
Another important factor is the conversion rate, which is the percentage of leads that actually become paying customers. If only 3% of your leads result in orders, this is a critical point for your ROI calculations. Understand how high this value is and how you can improve it.
8. Calculate the Final ROI
After entering all the data, you can now calculate your final ROI. If you find that you achieve a total of 450% ROI from €500 in advertising, this will be extremely important for your marketing strategy. A ROI of 450% means that for every euro you invest, you receive €4.50 back.
9. Optimize Your Strategy
Based on your calculations, you should continuously review and optimize your customer acquisition strategy. Look for ways to reduce costs per inquiry or increase the conversion rate. Each improvement directly contributes to a higher ROI.
10. Consider Long-Term Customer Relationships
Long-term customer relationships increase your Customer Lifetime Value and thus your ROI. Once a customer has built trust in your services, they are more likely to continue purchasing from you. Use email marketing to generate follow-up orders and thereby increase your profits.
Summary – Customer Acquisition through Facebook and Google AdWords: Calculating the Return on Investment (ROI)
To extract the best possible ROI from your advertising expenditures, precise calculation and strategic planning are essential. Be sure to consider the Customer Lifetime Value in order to get a complete picture of your advertising efficiency.
